Dear, visit the Ministry of Interior and try to take an Interview Date for you. No need to re-apply the application.

For me the case was same without any reason they rejected my family RP application even I had submitted all the necessary documents/requirements with RP application. Than I asked an interview date which they given me after around 45 days, then after 45 days I went for an interview and in this interview they just asked me about my accomodation that is this company provided or no. And after 1 day I checked my same application number on the MOI website, and I got approved.

That's all. Let me know if you need more info. Thx.
